IMPROVEMENT IIN VMEJI'ALLIC SEALS.

Specification forming part of Letters Patent No. 154,639, datedSeptember 1, 1874 application filed July 21, 1874. Y

To all whom it may concern Be it known that I, EDWARD J. Bn'ooKs,

of the city, county, and State of New York,

have invented a new and useful Improvement in Metallic Seals, of whichthe following isa specification My invention relates to that class oi'metallic seals which consist essentially of a wire one end of the wirebow, which end is formed with a loop or otherwise adapted to be firmlyheld within the lead, and passing the other end of the bow through theloop or bend Athus formed' in the fixed end of the bow, so that when thelead is lcompressed both ends may be firmly held. My improvementsconsist, secondly, in combining, with a bow of wire and a ball or diskof soft metal, one or more loops ofr hard metal in the form of wire orany other form adapted to produce thedesired ei'ect, said loops beingeast within the soft-metal ball or disk in such a manner that the endsof the bow, in passing through the perforations in the ball or disk,will pass through said wire loops, and the latter will thus be made,when the soft metal is compressed, to bear rmly-"upon the parts of thewire \bow, and eifectually prevent the separation of the latter from thelead.

In the accompanying drawings, Figure l is a perspective view of thecombined wire and leadpseal with thelead ball or disk east upon one endofthe wire. Fig. 2 is a section of the same', representing theperforation which passes through the lead ball or disk and the containedloop of the wire for the purpose ot'` receiving the free end of the bow.Fig. 3 is a section of the same in plane at right angles to that shownat Fig. 4Fig. 4 is a section thereof, showing the free end'ot' the wirebow inserted. Fig. 5 is anv elevation of thehuished seal. Fig. 6 is asection of the same. Fig. 7 is a section thereof in a plane at rightangles to that shown :at Fig. 6.' Fig. S is an bow, the end ot' the bowbeing introduced and the soft metal compressed thereon. Fig. 12 is anelevation ofthe wire in two parts, showing the-'holding-loop separate.from the bow. Fig. 13- is a section of the same with the lead cast uponthe loops in readiness for thev reception of the bow. Fig. 14 is asection of this form of seal'in its finished state.

A represents a loop of twisted wire', which, in Figs. l to 8, inclusive,is represented as formed with-a loop, a, at one end, the shape of whichis niore particularly shown in Fig. 3. Upon this loop end of the bow thelead ball or disk B is east, the perforation b, which is to receive thefree end'of the bow, passing through the loop. In Figs. 9 to 11,inclusive, the bow is shown with a double loop, a a, to which the leadball B is applied in a similar manner. In Figs. v12 to 14, inclusive,the loops a a are shown as formed of a separate piece ot' wire, Auponwhich the lead ball or disk B is cast with two perforations, eachpassing through one pair of loops. This form of the invention enablesthe wire bow to be' madeA without permanent connection with the leadball or disk.

In applying the invention under either of its modifications, the freeend or ends of the wire bow are passed through the perforations oftheball or disk B, and ythrough the bows therein contained, so that whenthe lead ball or disk isompressed upon the seal by any devicecustomarily employed for'such purpose the wire of which the 4parts a aare formed, and which is anchored firmly within the lead, will -becaused to grasp securely the parts of the bow A, while the soft metallocks the whole together. p This device will thus the possibility oi'the end or ends of the wire bow, enlarging the apertures in` the leadseal after the latter has been compressed upon them, so as to Vworkthemselves loose. My plan of surrounding the perforatious oi' the beseen to preclude lead hull or disk with :t hushingjof hard metal affordsat degree of perinaneney and security 'not heretofore provided in thisclass of seals.

rlhe lead ball or disk nifty Vhe faced or covered with a plate of sheetmetall suitably engraved or marked.

The following is claimed ats new:

1. The combination of u shackle wire", A. having" it looped end, :tud :tsoft-n'ietal bail or disk, B, cast upon the looped'end of the wire A,und pierced wit-h an aperture extending through the loop ofl the wire,substantially as and for the purpose set forth. l

2. The combination of a. ball or disk of soft. metal, zt' loop or loopsof hztrdmetal encircling' or bushing :m orifice in the soft metal, :uid:t wireto pass through the hushed oljfice, substantialljyT its setforth.A
